Let me be very clear, here, this show is awful. It has a contrived and awful plot, 2 dimmensional characters, and badly conceived monsters and enemies. And it is for those reasons that I love this show. You'll notice I rated it as bad, so don't get me wrong thinking I am trying to defend it or something. On the contrary, I want people to watch this show because it is awful.
Sometimes, in between all the drama and heart crushing plot of other, decent anime, you just need a terrible traffic light monster to lighten the mood and give you a good laugh. They probably didn't mean for me to be laughing at most of it, but like hell is that gonna stop me. No thinking, no discourse, just pure, unfiltered nonsense to help you sleep at night. It's the simple joys in life, ya know?
